Flinders University's Emma deCourcy-Ireland and Lachlan Palmer explain how they identified grains that were high in iron and zinc, using X-ray fluorescence Mass spectrometry, and why those nutrients are important.

Questacon's Sarah Clark demonstrates the principle of "protostorming" at the National Science and Technology Centre, quickly developing as many prototypes as possible of objects that move in the wind, using simple materials, and then refining those designs.
